Engine/CVT Integration Control (CAN Communication Control)

In order to improve gearshift feeling and to perform controls such as prevention of engine slowdown, engine power control signals are intercommunicated between the engine ECM and the TCM, and real-time cooperative controls depending on vehicle driving conditions are performed.

TCM sends information such as fast slowdown signals, lock-up signals, torque down request signals to ECM, while receiving information such as torque down permission/prohibition signals, lock-up permission/prohibition signals, throttle position from ECM.
